FIELD

The subject matter disclosed herein relates to a connector alignment andretention panel for an electronics housing. The connector alignment andretention panel can be used as part of a modular based system such as amodular, scalable linear motor system or any other system including oneor more electronics housings assembled from at least two interconnectedsections.

BACKGROUND INFORMATION

Historically, in power conversion products and other complex electricalsystems, multiple internal pluggable connections are required duringassembly as the different printed circuit board (PCB) subassemblies arebrought together and enclosed within a housing having first or upper andsecond or lower portions that are interconnected. Typically, theseinternal pluggable connections are accomplished using “flying lead” typeconnector structures in which a mating connector is located at the endof plurality of wires that are loosely connected to a first (or lower)housing portion or a second (or upper) housing portion. During assembly,enough slack is present in the flying lead connectors to allow the plugconnection to be completed before the first and second housing portions(or other housing portions) are connected together to completeconstruction of the housing in which the PCB subassemblies and otherelectrical component are contained.

These internal pluggable connections are difficult to implement in acompact product design in which space is limited because the flyingleads, themselves, take up excessive space and the plug connections aredifficult to complete or “make” when there is not enough room for anassembler to work. Also, each internal plug connection must be madeseparately. Furthermore, the required added length of the wires/cablesof the flying lead connectors increase the amount of electromagneticinterference (EMI) generated which can cause interference with nearbyelectronic components, and the unrestrained, lengthy wires/cables canexhibit wear or “fretting” over time due to repeated movements fromvibrations and the like. The foregoing issues and others can lead tofailures resulting from incomplete connections and/or connections thatare completely missed during the assembly process. Even if such failuresare caught during quality control testing, costly and time-consumingreassembly must be carried out to correct the problem(s). Also,unrestrained flying lead connectors can lead to reliability problems dueto EMI and also due to wire/cable fretting over time due to vibrationsand other incidental movement of the connectors during use of thesystem.

DETAILED DESCRIPTION

FIG. 1A is an isometric view of a modular, scalable linear motor tracksystem TS which is one example of a system in which a connectoralignment and retention panel according to the present development canbe used as described below. One example of such a linear motor tracksystem TS is available commercially from Rockwell Automation under theregistered trademark ITRAK®. The linear motor track system TS is amodular, scalable and linear motor system including a system housing SHin which electronic components are enclosed. The system housing SHcomprises a plurality of modular housing assemblies including one ormore straight housing assemblies HA and one or more curved housingassemblies HB that are interconnected to construct and define the systemhousing SH. The system housing SH comprises a rail R and the linearmotor track system TS comprises at least one and typically multiplemovers M (only one shown) that are operably movably engaged with therail R. The one or more movers move bi-directionally along the rail R asindicated by the arrow A in a feedback-controlled manner as controlledby the motor electronics in the system housing SH. When multiple moversM are operably installed, they can be synchronized to move in unisonwith respect to each other or they can be independently controlled andmove independently with respect to each other, depending on programming.

FIGS. 1B and 1C are respective isometric views of the straight (first)and curved (second) electronics housing assemblies HA,HB (generallyhousing assemblies H) shown in FIG. 1A that can be used individually orthat can be connected together with one or more other housing assembliesas described above to define a housing enclosure such as the systemhousing SH.

In either case HA,HB, the housing assembly H comprises at least twosections or portions including a first (lower) housing or housingportion H1 and a second (upper) housing or housing portion H2 that areinterconnected by fasteners (screws, pins, clips, rivets, etc.), matingprojections, adhesive, welding/bonding, and/or other suitable devices,structures and/or means. When operably interconnected as shown in FIGS.1A and 1B to define a housing assembly HA,HB, the first (lower) andsecond (upper) housing portions H1,H2 define and at least partiallyenclose an internal space S (FIGS. 2A & 2B) that contains electroniccomponents such as electronic devices, motors, fans, printed circuitboards (PCBs), switches, and the like.

FIGS. 2A and 2B respectively show the first and second housingassemblies HA,HB with their second (upper) housing portion H2 removedfrom the first (lower) housing portion H1 to reveal a connectoralignment and retention panel P (P1 for the housing HA of FIG. 2A, P2for the housing HB of FIG. 2B). The connector alignment and retentionpanel P (P1,P2) is fixedly secured to the first (lower) housing portionH1 and is operatively engaged with and retains one or more flying leadconnectors C of the first housing portion H1 in a select position sothat the panel P operatively locates and retains the flying leadconnectors C in a select location and orientation with respect to thefirst housing portion H1 to which the panel P is connected. Inparticular, each connector C engaged with and retained by the panel P isoperatively located in a select, predetermined position relative to thefirst housing portion H1 with respect to all of the X,Y,Z axes of aconventional three-dimensional axis coordinate system, wherein axis Z isparallel to a connection axis CX (FIG. 7) along which the connector Cmates with a mating connector and the axes X and Y being coplanar witheach other and arranged perpendicular with respect to each other andeach also being perpendicular to the Z axis. The connectors C held bythe panel P are operatively positioned to mate with correspondingconnectors CMCa,CMCb (see FIG. 7) connected to and carried by the second(upper) housing portion H2 when the second (upper) housing portion 112is connected to the first (lower) housing portion H1 when the first andsecond housing portions H1,H2 are aligned and connected to each other.This mating of the connectors C (MCa,MCb) held by the panel P with thecorresponding connectors CMCa,CMCb carried by the second housing portionH2 occurs in a single step as part of the process of connecting thesecond housing portion H2 to the first housing portion H1 and does notrequire an assembler to mate the connectors MCa,CMCa and MCb,CMCb priorto connecting the second (upper) housing portion H2 to the first (lower)housing portion H1, i.e., the connectors MCa,CMCa and MCb,CMCb are matedin a single-step when the second (upper) housing portion H2 is movedaxially along the Z axis in a connection direction CD toward and intomating abutment with the first (lower) housing portion H1.

With continuing reference to FIGS. 2A and 2B, and also referring toFIGS. 3A and 3B, the panel P (P1,P2) comprises a one-piece polymericbody 10 defined by an injection molding process, an additivemanufacturing process, extrusion process, thermoforming process, and/orother polymeric forming process. The panel P is electricallynon-conductive and thus exhibits electrical insulation properties.

The panel body 10 comprises a connector support platform 12 and aplurality of support legs 14 that are connected to a peripheral edge ofthe connector support platform 12 and that extend transversely outwardlyaway from the connector support platform 12. At least one leg 14includes, and preferably two or more of the legs 14 include, an outerend 14 a that comprises a foot 14 b that extends transversely outwardfrom the outer end 14 a of the leg 14 and that includes a mountingopening 14 c such as an aperture, slot, or notch defined therein that isadapted to receive a screw or other fastener. The panel P is fixedlysecured to one of the housing portions H1,H2 (the first housing portionH1 as shown in the present example) by fasteners F installed through themounting opening 14 c of each foot 14 b (FIG. 7). Alternatively, thefeet 14 b can be inserted into notches or other receiving locationsincluded in the first housing portion H1 by resilient flexing of thelegs 14 such that the panel P is fixedly secured to the housing portionH1 without using fasteners.

FIGS. 4-6 are respective top, bottom, and isometric views of theconnector alignment and retention panel P(P1) of the present embodiment.FIG. 7 is a section view as taken at section line 7-7 of FIG. 1A thatillustrates operative use of the panel P to connect one or more PCBs orother electronic elements E1 connected to the first (lower) housingportion H1 to one or more PCBs or other electronic elements E2 connectedto the second (upper) housing portion H2. It can be seen in these viewsthat that the connector support platform 12 includes opposite first(inner) and second (outer) surfaces 12 a,12 b. The first (inner) surface12 a is oriented inwardly toward the first housing portion H1 while thesecond (outer) surface 12 b is oriented outwardly away from the firsthousing portion H1. The connector support platform 12 of the panel P israised or vertically offset along the Z axis relative to the feet 14 bto position to connectors C at a proper location along the Z axis formating with the corresponding connectors MCa,MCb carried by the second(upper) housing portion H2. Accordingly, a panel space PS is definedunder the first (inner) surface 12 a between the inner surface 12 a ofthe raised connector support platform 12 of the panel P and the firsthousing portion H1 to accommodate PCBs and other electronic devices E1carried by the first housing portion H1. The panel P includes voids,openings, and other panel openings PO defined through the connectorsupport platform 12 and also defined in the body 10 adjacent the legs 14and around a peripheral edge of the connector support platform 12 sothat the panel space PS is in fluid communication with the space Sdefined in the housing HA,HB so that air can flow freely into and out ofthe panel space PS to cool the PCBs and other electronic componentscarried by the first (lower) housing H1 and located in the panel spacePS.

The panel P may include one or more partition walls PW that areconnected to and that extend transversely outward from the inner and/orouter surfaces 12 a,12 b of the connector support platform 12 and thateach provide or define an air baffle to block air flow, direct ordeflect air flow, and/or route air flow in a desired direction and witha desired air flow velocity relative to the panel P. One or more of suchpartition walls PW can also be used to physically isolate, protectand/or electrically insulate/isolate or shield one or more electroniccomponents E1 in the panel space PS and/or supported on the connectorsupport platform 12 from other such electrical components. The connectorsupport platform 12 of the panel P also includes or defines one or morecomponent mounting locations 16 (FIGS. 3A & 3B) such as recesses or flatsurfaces that each provide a mounting location for any desiredelectrical component such as a fan, a switch, an indicator LED, a heatsink, or any other desired component.

The panel P can include first and second high frequency signalconnectors SCa,SCb connected thereto. The first and second signalconnectors SCa,SCb are operably electrically interconnected by a cablesuch as the illustrated ribbon cable RC. The second (outer) surface 12 bof the connector support platform 12 includes a second signal connectormounting locations 40 b (see also FIGS. 3A and 3B). The second signalconnector mounting location 40 b is dimensioned and conformed to closelyreceive and retain the second control signal connector SCb such as witha snap-fit, friction fit, or other mechanical engagement. In theillustrated embodiment, the second signal connector mounting location 40b includes one or more resilient tabs 40t (FIGS. 3A and 3B) that retainthe respective signal connector SCb in an operative position on thepanel P with a snap fit. Preferably, the signal connector mountinglocation 40 b is dimensioned to retain the signal connector SCb whilealso allowing limited movement of the connector SCb relative to thepanel P along both the X and Y axes which are oriented transverserelative to the Z axis along which the connector SCb mates with acorresponding connector. This limited movement of the connector SCbrelative to the panel P along both the X and Y axes allows the secondsignal connector SCb to move as required during the process of matingwith a corresponding signal connector to accommodate or adapt to anymisalignment between the connector SCb and the corresponding matingconnector. The first high frequency signal connector SCa can be securedto the first side 12 a of the connector support platform 12 in the samemanner that the second signal connector 14 b is secured to the secondside 14 b of the platform 12 but, as shown herein, the first signalconnector SCa is not directly fixedly secured to the panel P. Instead,the first signal connector SCa is indirectly connected to the platform12 of the panel P by way of its connection to the second signalconnector 40 b via cable RC. Thus, the first signal connector SCa isindirectly connected to the panel P via cable RC and is movable relativeto the panel P.

As shown herein, the first and second control signal connectors SCa,SCbare high frequency signal connectors operatively electrically connectedto each other by a cable such as the illustrated ribbon cable RC thatextends through the panel space PS between the first and second signalconnectors SCa,SCb to electrically interconnect the control signalconnectors SCa,SCb. The panel P includes one or more slots or passages42 for receiving and retaining the ribbon cable RC as it extends betweenand operatively interconnects the first and second signal connectorsSCa,SCb.

The outer surface 12 b of the connector support platform 12 furtherincludes at least one and preferably two or more motor (or other)connector mounting locations 50 a,50 b (generally 50). Each motorconnector mounting location 50 a,50 b is dimensioned and conformed toclosely receive and retain a motor (or other) connector MC (MCa,MCb)such as the illustrated 10 pin motor plugs with a snap-fit, frictionfit, or other engagement. In the illustrated example, the motorconnector mounting locations 50 a,50 b thus each include one or moreresilient tabs 50t that retain the respective motor connector MCa,MCbwith a snap fit. Preferably, the motor connector mounting locations 50a,50 b are dimensioned to retain the respective connectors MCa,MCb whilealso allowing limited movement of the connector MCa,MCb along both the Xand Y axes which are oriented transverse relative to the Z axis alongwhich the connector MC mates with a corresponding connector. Thislimited movement of the connectors MCa,MCb along both the X and Y axesallows the connectors MCa,MCb to “float” or move as required during theprocess of mating with a corresponding connector CMCa,CMCb toaccommodate or adapt to any misalignment between the connector MC andthe mating connector CMCa,CMCb.

As shown in the present embodiment, each connector mounting location 50includes four corner regions 52 a,52 b,52 c,52 d that extendingperpendicularly outward from the upper surface 12 b of the platform 12to define a rectangular connector receiving region that receives andretains the connector MCa,MCb while allowing for limited movement of theconnector MCa,MCb in the connector receiving region along the X and Yaxes (the corner regions 52 can be separate from each other and providedas post structures or the corner regions can be interconnected to definea wall structure between themselves, both of which arrangements areshown in FIG. 4).

As best seen in FIGS. 2A, 2B, and 7, each panel P (P1,P2) includes oneor more cable routing channels CC in communication with the connectormounting locations 50 a,50 b that receive and retain the cables or wiresCB connected to the motor connectors MC. These cable routing channels CCeach provide a groove, channel, or other recessed location that receivesthe connector cables CB to provide space for the cables CB, to protectthe cables CB prevent contact between the cables CB and adjacentcomponents, and locate the cables CB in their optimum positions to allowthe second (upper) housing H2 to be connected to the first (lower)housing H1 without interference between one or more of the cables CB andthe second (upper) housing 112. These cable routing channels CC ensurethat the cables CB are always positioned as desired for optimum assemblyof the housings HA,HB and to protect the cables CB from wear over timeduring use due to repeated shocks and vibrations.

The section view of FIG. 7 illustrates operative use of a panel P toconnect a first group of one or more PCBs or other electronic elementsE1 carried by the first (lower) housing portion H1 to a second group ofone or more PCBs or other electronic elements E2 carried by the second(upper) housing portion 112. FIG. 7 shows the straight panel P1, butthose of ordinary skill in the art will recognize that the curved panelP2 operates in a corresponding manner. In FIG. 7, it can be seen thatthe panel P is fixedly secured to the first (lower) housing H1 by aplurality of screws or other fasteners F respectively installed throughthe mounting opening 14 c of a corresponding plurality of feet 14 b andengaged with the housing H1. As such, the open panel space PS is definedbetween the inner surface 12 a of the platform 12 of the panel and thehousing H1. At least some of the first group of electronic elements E1carried by the first (lower) housing portion H1 are located in the panelspace PS.

As noted above, the first and second signal connectors SCa,SCb areconnected to the panel P and are interconnected by a ribbon cable RC(the ribbon cable RC is omitted from FIG. 7 but is shown in FIGS. 4-6).The panel P positions the first and second signal connectors SCa,SCb intheir respective required positions to mate respectively withcorresponding signal connectors CSCa,CSCb that are part of theelectronic elements E1,E2 carried by the first and second housings H1,H2when the first and second housings H1,H2 are connected together duringassembly. As such, it can be seen that the first signal connector SCalocated in the panel space PS is operatively mated with a firstcorresponding signal connector CSCa carried by a PCB in the first(lower) housing H1 as part of the first group of electronic elements E1,and the second signal connector SCb located on the outer side 12 b ofthe connector support platform 12 of the panel P is operatively matedwith a second corresponding signal connector CSCb carried by a PCB inthe second (upper) housing H2 as part of the second group E2 ofelectronic elements. This results in the first and second correspondingsignal connectors CSCa,CSCb of the first and second housings H1,H2 beingoperatively electrically connected to each other by way of the ribboncable RC and the signal connectors SCa,SCb located on the opposite endsof the ribbon cable RC (the cable RC need not be a ribbon cable and canbe any other electrical signal cable).

Similarly, the first and second motor connectors MCa,MCb are operativelyconnected to the panel P via the first and second connector mountinglocations 50 such that the first and second connectors MCa,MCb areoperatively positioned to mate respectively with the correspondingconnectors CMCa,CMCb carried by the second (upper) housing H2 as part ofthe second group of electronic elements E2. Those of ordinary skill inthe art will recognize that the connectors MCa,MCb are positioned by thepanel P such that they are properly operatively positioned to mate withtheir respective corresponding connectors CMCa,CMCb along theirconnection axis CX when the second (upper) housing H2 is mated with thefirst (lower) housing H1 during assembly of the overall housing HA,HB.In the illustrated embodiment, the first and second connectors MCa,MCbare located at the distal ends of respective flying lead cable bundlesFLa,FLb each comprising a plurality (bundle) of the wires CB thatoriginate at respective plugs PG or other electronic elements E1 carriedby the first (lower) housing H1. The flying lead cable bundles FLa,FLbare safely retained by the panel P in the cable routing channels CC ofthe panel P to prevent movement of and otherwise control the position ofthe cables CB relative to the panel P and housing H1 and to protect thecables CB from fretting or other damage.

It should be noted that during disassembly, the second (upper) housingH2 is separated from the first (lower) housing H1 by movement of thesecond (upper) housing H2 along the Z axis away from the first (lower)housing H1. Such movement of the second (upper) housing H2 away from thefirst (lower) housing H1 along the Z axis causes disconnection of thefirst and second connectors MCa,MCb secured to the panel P from theirrespective first and second corresponding connectors CMCa,CMCb carriedby the second (upper) housing H2 and also causes disconnection of thesecond signal connector SCb secured to the panel P from itscorresponding signal connector CSCb carried by the second (upper)housing H2.

In the preceding specification, various embodiments have been describedwith reference to the accompanying drawings. It will, however, beevident that various modifications and changes may be made thereto, andadditional embodiments may be implemented, without departing from thebroader scope of the invention as set forth in the claims that follow.The specification and drawings are accordingly to be regarded in anillustrative rather than restrictive sense.
